Problems solved by technology

[0005] PCI Conflict: Please refer to figure 1 , PCI conflict means that the same PCI cannot be used between two adjacent cells; if two adjacent cells use the same PCI, in the over-area coverage area, the terminal can only synchronize with one cell, and it will cause the following problems : Synchronize the downlink of the delayed UE (User Equipment, user equipment) in the overlapping coverage area; cause high block error rate, physical channel decoding failure; handover failure
[0010] At present, there are few researches on PCI self-configuration and self-optimization in the industry, basically only involving PCI self-configuration, and basically all of them are centralized management, which does not conform to the self-configuration and self-optimization idea of ​​SON

Embodiment 1

[0075] Please refer to image 3 , Figure 5 to Figure 7 , a method for PCI self-configuration and self-optimization, comprising steps:

[0076] S1. Collect neighbor cell lists within two hops of the base station site, and classify the neighbor cell lists within two hops.

[0077] Specifically, PCI self-configuration mainly self-configures the initial PCI when the base station is built, and PCI self-optimization mainly adjusts the PCI during the operation of the base station. Therefore, the collection of neighboring cells includes the collection of neighboring cells during station construction and the collection of neighboring cells during operation.

[0078] Wherein, the collection of neighbor cell lists within two hops of the base station site includes:

[0079] Listening to the neighbor cell information within the coverage area when the base station site is built;

[0080] Establishing a signaling node for the intercepted neighbors, collecting the one-hop neighbor list of...

Embodiment 2

[0104] The difference between this embodiment and Embodiment 1 is that it further defines how to determine whether to optimize the PCI configuration, specifically:

[0105] Judging whether to optimize the PCI configuration of the site according to the changes in the site and its neighbors includes:

[0106] When it is detected that the station changes or when it is detected that the neighboring cells of the station change causing conflict and confusion, or when the monitoring index of the station is detected to deteriorate, it is determined whether the PCI configuration of the station needs to be optimized.

[0107] A site change refers to a change in site parameters, including but not limited to manually changing the site PCI / site frequency point / site two-way neighbor switch, manually changing the neighbor list, and UE neighbors report to change the neighbor list.

[0108] A change in a neighboring cell means that a neighboring cell is newly added or a neighboring cell parame...

Embodiment 3

[0121] Please refer to Figure 4 , a PCI self-configuration and self-optimization device, comprising a memory, a processor, and a computer program stored on the memory and operable on the processor, when the processor executes the computer program, the first embodiment or implementation is realized Various steps of the PCI self-configuration and self-optimization method in Example 2.

[0122] In summary, the present invention provides a method and device for self-configuration and self-optimization of PCI, which collects and classifies the list of neighboring cells within two hops of the base station site. Self-optimization is mainly to adjust the PCI during the operation of the base station. Therefore, the neighbor cell collection includes the neighbor cell collection of the station construction and the neighbor cell collection during operation, and can accurately obtain the neighbor cell information of the current base station; each distributed station detects a station or a...

Abstract

The invention discloses a PCI self-configuration and self-optimization method and device, according to which, neighbor cell lists in two hops of a base station site are collected and classified, self-judgment is carried out according to the change conditions of the site and neighbor cells of the site, whether PCI configuration needs to be optimized or not is judged, if PCI optimization needs to be carried out, a PCI value is determined through a PCI selection algorithm of a multivariate model on the basis of the neighbor cell lists in the two hops, PCI self-optimization is realized so as to reduce the occurrence of PCI conflicts and confusion, thereby improving the network performance of the base station site.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a PCI self-configuration and self-optimization method and device. Background technique [0002] With the large-scale advancement of 5G network construction, the situation of 5G sites changes extremely frequently. Ultra-dense networks will be a trend in 5G communication systems. The structure of cells will be miniaturized and distributed, and the mutual cooperation between cells will become more and more more important. With the substantial increase of sites, the complexity of network management far exceeds that of the existing LTE network. Network intelligence has become an urgent need to ensure 5G network performance. SON (Self Organizing Network, self-organizing network) will become an indispensable key technology for 5G . [0003] SON refers to the self-organization capability of the network, and has three main functions: self-configuration, self-optimization,...
